|Title:||CP violation in top quark production at the LHC and two-Higgs-doublet models|
|Publisher:||Elsevier Science B.V.|
|Abstract:||We discuss CP violation in top-antitop production at the LHC, induced by gluon fusion and final-state Higgs exchange. Results by Bernreuther and Brandenburg are confirmed and further reduced. The lepton energy asymmetry is studied in detail in explicit Two-Higgs-Doublet Models with near-maximal mixing in the neutral Higgs sector. Unless there is only one light Higgs particle, and unless (in “Model II”) tan β <∼ 1, the CP-violating effects are very small, possibly too small to be seen at the LHC.|
